Serum free light chains increased ratio normal. lambda immunofixation with 4% m spike in beta 2 region in urine only. recommended next step 4 anemia?
Testing for AL amyloid. SPEP shows no M-spike but mildly elevated total protein & A/G ratio (2.7) due to high albumin. Globulins well within normal range. Worrisome? Serum/urine IFE &marrow biopsy ok, but elevated free K/L ratio due to low lambda.
Kappa (4 vs ref 2mg/dl) and sometimes lambda light chain in 24hr urine without mm. What can be suspected? Anemia, worsening ckd, improves with na co3
Can stress cause higher serum light chain numbers? Kappa slightly elevated (21.5), lambda normal, k/l ratio normal. Kappa, lambda, k/l ratio in urine all normal. No M protein observed. I have stress and anxiety..just wondering if this could affect.
Serum free light chain test shows normal kappa (8.7mg/dl), low lambda (3.80), high kap/lam ratio (2.31). Serum $ urine electrophoresis show no monoclonal protein, nor does serum immunofixation. Likely MGUS, myeloma, or admyloidosis? CBC/met panel ok.
